Officials from Richard Petty Motorsports announced Tuesday that the Des Moines native Annett will be out of racing indefinitely due to injuries he suffered Saturday afternoon in the Nationwide Series race at Daytona.

"After further evaluation by two different doctors in North Carolina, it has been determined that Richard Petty Motorsports driver Michael Annett has suffered a fracture and dislocation of his sternum," Petty Motorsports said in a statement. "He will immediately undergo surgery for his injuries in Charlotte."

Annett was a guest on the 1700am The Champ radio show "Out of Bounds with Andy Garman and Larry Cotlar" on Monday afternoon. Annett spoke about his injuries, saying that he felt what "looked like a golf ball on my sternum." But after several medical checks, including an MRI exam, Annett said he believed that he'd be sore, but ready to race at this weekend's Nationwide Series race in Phoenix this weekend.

Annett is said to be out of racing indefinitely. His race team expressed concern for "the health of Annett and getting him the proper treatment he needs for a full recovery."
